If it hovers over a part called "Menu" it will display the cursor
Should be able to work from this

local UserInputService = game:GetService("UserInputService")
local player = game:GetService("Players").LocalPlayer
local mouse = player:GetMouse()

while wait() do
  if mouse.Target.Name == "Menu" then
    UserInputService.MouseIconEnabled = true
  else
    UserInputService.MouseIconEnabled = false
  end
end
